Fade Margin Chart
What’s an acceptable “Link Margin“? An accepted theory is that 10 dB of
fade margin will deliver a 90% reliability and 20 dB will deliver a 99% reliability
etc.. There are other factors that affect this including vertical or horizontal polarization. At 2.4 GHz there is only a small ground wave component involved
in the radio propagation. This means that the above numbers are presuming
clear LOS (line of sight). Multi-path occurs when a reflector such as earth’s
terrain or man made structures cause additional delayed signals to be received. If a signal was delayed 180 degrees out of phase with the line of sight
signal, and the magnitudes are the same, they will cancel out completely! In
the real world, if you do have line of sight path, multi-path degradation is the
reason why you need a minimum of 6 to 10 dB of margin. If you don’t have
line of sight, multi-path could easily cause 20 dB of degradation.

(2) Other users of the 2.400 to 2.483 GHz ISM band.
The ISM or Industrial, Scientific, and Medical band, is shared with many other
type of services. Fortunately most of the users are located in urban areas,
leaving sharing concerns down to consumer microwave ovens and other
spread spectrum rural telephone users. The I-WLL-15 system has divided the
ISM band into 8 sub-bands or channels. One channel is used for system administration with the system then randomly selecting 1 of the 7 remaining
channels for operation. The functionality of the i-WLL–15 system depends on the existing and forecasted spectrum usage in the radio
path. Due to the characteristics of the spread spectrum radio, the ITU
(International Telecommunication Union) was able to coordinate this band
globally for unlicensed use. This means that any user has to accept all other
users in this band, interfering or not.
(3) Availability of telephone service and power.
The I-WLL-15 system consists of two units. One is designed to connect to
the standard phone lines provided by a local telephone company office (FXO
side) and the other connects to the telephone instruments such as; DTMF
(touch tone) telephones, fax machines, and computer modems (FXS side) via
individually twisted pair phone/data cable. The system is very flexible about
voltage requirements. 12 to 55 Volts DC with the current being inversely proportional to the voltage, the power use being approximately 3 Watts for the
FXO side, in any state, and 3 to 6 Watts for the FXS side depending on usage state. We recommend over-sizing the supply by 1.5 to 2 times. Depending on the length, most installations can use 4 twisted pair, #22 AWG feed
cable. This will drop about 1 volt per 100 feet of length. To allow for most any
voltage drop situation we recommend 24 volt, 500 mA power supplies. Using
non-twisted IW or Quad phone wiring will result in cross-talk between
lines.
(4) Mounting structure.
Warning! Use extreme caution to avoid contact with any high voltage
power lines when constructing antenna structures!
The enclosure is designed to mount on a steel vertical pipe, commonly known
in North America as 1 to 2 inch pipe ( 2.5 to 5 cm ), with an actual outside
diameter of 1.3 to 2.5 inches ( 3 to 6 cm ). This mast must not move significantly in any anticipated wind and must be connected with a short copper #8
AWG wire to a copper clad ground rod driven at least 6 feet (2m) into moist
earth.

Carlson Wireless USA revision 1.05 Page 7
INSTALLATION
Note that the installation of the FXO and FSO units are similar
(1) Connecting the feed cable to the outside unit. On the mounting end of
the tube there is an end cap with a weather sealing clamp. This allows the
feed cable the penetrate the housing and remain sealed to outside weather.
Begin with the removal of the rear end cap by using a coin as a wedge and
working your way around the tube until the end cap pops off. Inside the end is
the electronics assembly consisting of the printed circuit boards and integrated antenna. There are two screw down terminal blocks on the exposed
end. One block has 2 connections and it is where the DC power supply connects. The other block has 4 connections, for telephone lines 1 and 2. The
following diagram shows how to wire the connectors. Make sure to hand
tighten only the weather sealing cord grip.
Note: Make sure that the antenna elements are vertical or perpen-

(3) Lightning protection. Grounding of the drain wire: For feed cable runs of
less than 35 feet (10m) and not located in a highly active lightning area, connecting the bare drain wire to a copper clad ground rod driven at least 6 feet
(2m) into moist earth with a short copper #8 AWG wire at the point of the terminal block may suffice. The antenna mast must also be grounded in the
same fashion by a separate grounding rod. However if the run is longer than
35 feet or the location is in a highly active lightning area then a standard 3
way gas tube protector must be added. Connecting information on this device
is provided by it’s manufacturer.

(4) Rough alignment. This is usually easier then it would seem. Since it is a
prerequisite that you have line of sight between the two points, here are several ideas that have worked for installers:
(1) If you can see the other unit, simply aim the tubes towards each other. (2)
During midday, use a large mirror to create a bright reflection approximately
towards the other site while someone watches for the flash.
(3) Plot out the path on a topo map and set the antennas using a compass.
How close in alignment do they need to be? +/- 10 degrees will be adequate for most paths using the 13.5 dB gain antenna. Certain paths that have
a low fade margin may require a more accurate setting.
Final alignment. This is usually done by connecting a standard cordless
phone to the FXS or FXO end, and then give a best guess to the direction,
establish a connection and rotating the antennas both right and left noting the
points where the signal disappears, (assuming that it does) and then centering them between those cutoff points.
Remember to leave the antenna elements vertical, or perpendicular to
the ground for best performance
TROUBLESHOOTING
The outcome of the installation is dependent on the weakest link.
Five things are paramount to his system working well:
(1) An acceptable radio path
(2) Other users of the 2.4 GHz ISM band.
(3) Customer’s wiring of power and telephone circuits
(4) Antenna alignment within +/- 10 degrees for i-WLL-15
(5) Quality of the telephone lines from the telephone company
(6) Quality of the power supplies.
If the system appears dead, with no tones audible on the subscriber phone,
look for a wiring fault. You can test for loop voltage at the FXS end by measuring the voltage on line 1 and line 2. Each should be 30 VDC. Next would be
checking the DC current used by each unit. For example the sub unit with 16
Volts provided should draw (3W / 16V) ~200 mA. at idle and ~400 mA with
both lines off hook. This test is very useful to prove out the wiring.
Next, it will be important to confirm that a local test at the FXO base site was
done. If not, you will need to bring the FXS unit back to the base site and
temporarily connect the FXS unit up and confirm proper local operation.
If the system cuts in and out, or fails to draw dial tone, look for an alignment
problem or path obstruction. Also you should check to see that the antenna
elements are vertical to earth, and if not in a rural area you may have a congested frequency band.
If you are having cross-talk between lines, examine the phone cabling making
sure it is individually twisted pairs, preferably with a Category 5 rating.
Software Updates: Inappropriate operations (bugs) reported by users will be
evaluated by the engineering department. Fixes will be available from our web
site with instructions
If after checking the above, you are still having problems please contact our
sales dept. for technical assistance by phone or email. A note about the
power supplies: The FXO unit will draw 2-3W off hook or idle. The sub will
draw 3W idle and 6W with both lines off hook. We suggest over-sizing the
supplies by 2 times. For example a 12 volt filtered DC wall transformer supply
@ 1.00 Amp (12W) or even better a 24 volt filtered DC @ 500 mA. (12W).
They are much more likely to survive power fluctuations and high temperaCarlson Wireless USA revision 1.05 Page 10

(3) Lightning protection. Grounding of the drain wire: For feed cable runs of
less than 35 feet (10m) and not located in a highly active lightning area, connecting the bare drain wire to a copper clad ground rod driven at least 6 feet
(2m) into moist earth with a short copper #8 AWG wire at the point of the terminal block may suffice. The antenna mast must also be grounded in the
same fashion by a separate grounding rod. However if the run is longer than
35 feet or the location is in a highly active lightning area then a standard 3
way gas tube protector must be added. Connecting information on this device
is provided by it’s manufacturer.

INSTALLATION
Note that the installation of the FXO and FSO units are similar
(1) Connecting the feed cable to the outside unit. On the mounting end of
the tube there is an end cap with a weather sealing clamp. This allows the
feed cable the penetrate the housing and remain sealed to outside weather.
Begin with the removal of the rear end cap by using a coin as a wedge and
working your way around the tube until the end cap pops off. Inside the end is
the electronics assembly consisting of the printed circuit boards and integrated antenna. There are two screw down terminal blocks on the exposed
end. One block has 2 connections and it is where the DC power supply connects. The other block has 4 connections, for telephone lines 1 and 2. The
following diagram shows how to wire the connectors. Make sure to hand
tighten only the weather sealing cord grip.
Note: Make sure that the antenna elements are vertical or perpen-

(2) Other users of the 2.400 to 2.483 GHz ISM band.
The ISM or Industrial, Scientific, and Medical band, is shared with many other
type of services. Fortunately most of the users are located in urban areas,
leaving sharing concerns down to consumer microwave ovens and other
spread spectrum rural telephone users. The I-WLL-15 system has divided the
ISM band into 8 sub-bands or channels. One channel is used for system administration with the system then randomly selecting 1 of the 7 remaining
channels for operation. The functionality of the i-WLL–15 system depends on the existing and forecasted spectrum usage in the radio
path. Due to the characteristics of the spread spectrum radio, the ITU
(International Telecommunication Union) was able to coordinate this band
globally for unlicensed use. This means that any user has to accept all other
users in this band, interfering or not.
(3) Availability of telephone service and power.
The I-WLL-15 system consists of two units. One is designed to connect to
the standard phone lines provided by a local telephone company office (FXO
side) and the other connects to the telephone instruments such as; DTMF
(touch tone) telephones, fax machines, and computer modems (FXS side) via
individually twisted pair phone/data cable. The system is very flexible about
voltage requirements. 12 to 55 Volts DC with the current being inversely proportional to the voltage, the power use being approximately 3 Watts for the
FXO side, in any state, and 3 to 6 Watts for the FXS side depending on usage state. We recommend over-sizing the supply by 1.5 to 2 times. Depending on the length, most installations can use 4 twisted pair, #22 AWG feed
cable. This will drop about 1 volt per 100 feet of length. To allow for most any
voltage drop situation we recommend 24 volt, 500 mA power supplies. Using
non-twisted IW or Quad phone wiring will result in cross-talk between
lines.
(4) Mounting structure.
Warning! Use extreme caution to avoid contact with any high voltage
power lines when constructing antenna structures!
The enclosure is designed to mount on a steel vertical pipe, commonly known
in North America as 1 to 2 inch pipe ( 2.5 to 5 cm ), with an actual outside
diameter of 1.3 to 2.5 inches ( 3 to 6 cm ). This mast must not move significantly in any anticipated wind and must be connected with a short copper #8
AWG wire to a copper clad ground rod driven at least 6 feet (2m) into moist
earth.

Fade Margin Chart
What’s an acceptable “Link Margin“? An accepted theory is that 10 dB of
fade margin will deliver a 90% reliability and 20 dB will deliver a 99% reliability
etc.. There are other factors that affect this including vertical or horizontal polarization. At 2.4 GHz there is only a small ground wave component involved
in the radio propagation. This means that the above numbers are presuming
clear LOS (line of sight). Multi-path occurs when a reflector such as earth’s
terrain or man made structures cause additional delayed signals to be received. If a signal was delayed 180 degrees out of phase with the line of sight
signal, and the magnitudes are the same, they will cancel out completely! In
the real world, if you do have line of sight path, multi-path degradation is the
reason why you need a minimum of 6 to 10 dB of margin. If you don’t have
line of sight, multi-path could easily cause 20 dB of degradation.
